Old school specs?

[Parentnoia]

I was wondering if anyone had specs for the older 12" RFP2SVC. The ones from when they still said PUNCH across the cone. I'd especially like to know the ohm rating.

You talking about this model?

The spec's are on the page.

Well mine dont got the fancy silver magnet cover, but yeah. How'd you find that page? I frequented RF's site for month after I got the sub and all I could ever find was the DVC model.

Google, and i seperated RFP2SVC. to Rockford Fosgate P2SVC 12" and sure enough, that link came up.

Thank you for find it btw. One more quick question. If I wire a 4ohm in parallel with a 2ohm, what would the rating be? Like, what's the rudimentary mathematical formula for calculating a parallel ohm rating. I know series is one rating plus another rating.

That's over my head, got me beat on that. I know one of the braniac's that rome the forums can answer that for you.

Mmkay, thanks for being honest rather than attempt to pull something out of your @$$.

Anyone?

Are you talking about 2 subs? By the way, your amp would see 1.33 ohms, but each speaker would get different amounts of power.

Your formula is (for parallel): Resistance = (Speaker A x Speaker X) / (Speaker A + Speaker X)

Edit for smiley faces in my equation rather than letters...

Just don't do it, it's not smart to use 2 different woofers.
